Patent GB-2214057-A (GB)
Title: Absorbent garment
Inventor: SALMON MICHAEL ANTHONY
IPC: A61F13/15
Filed: 1989-01-23
Abstract: An absorbent garment of the type typified by a baby napkin and which comprises a pad 11 which includes superimposed layers of a liquid-impervious material, a liquid-absorbent material and a liquid-pervious material, is rendered more comfortable and less prone to leakage by securing each of at least one pair of opposite edges of the pad between two layers 13 of an elastomeric material in sheet form. In an illustrated example, a folded length of an elastomeric polyetherester material is adhesively secured over each of the opposite longer edges of a generally rectangular pad, which edges define the leg openings in use. The shorter edges of the pad may be sealed against fluid loss by inserted narrow strips 14 of liquid-impermeable polythene. Fastening tapes are secured to tabs 15.   <IMAGE>

Title: Determining the fundamental frequency of a signal
Inventor: WISDOM PAUL
IPC: G01R19/175
Filed: 1989-04-18
Abstract: A method for identifying the fundamental frequency of a signal, e.g. a note from a vibrating string (1) comprises providing (23) a signal corresponding to the note; detecting (4a,b) when a parameter of the signal changes from a positive to a negative value and vice versa so as to provide corresponding pulses; and passing the pulses to a bistable switch (5) which produces pulses whose frequency corresponds to the fundamental of the note being monitored. Detectors (4a, 4b) are positive and negative peak detectors. Pulses from the bistable (5) are applied to gates (8a, b) responsive to positive and negative half waves. The gates control clock pulses (7) to counters (9a, b) whose counts are converted to frequency using look-up devices (10a, b). The frequency values are transferred to registers (11a, b), and are compared (12) for validity checking prior to output (14). The method may be applied to acoustic, electrical and optical signals. <IMAGE>

Title: Delay line frequency discriminator
Inventor: SKIDMORE D S
IPC: G01S7/02
Filed: 1989-09-05
Abstract: RF input 20 in split 14 into two components fed to a recombining coupler 15, one via a delay line 17. Coupler 15 provides two signals each containing both components to two detectors 18,19 whose outputs are differenced (not shown) to provide a highly linear discriminator. The detector outputs are combined to control diode 23 to maintain the input level constant. Further linearising is achieved by compensating for reflections at mismatches in the detectors. The circuit is constructed in microstrip form and provided with absorbent material to prevent spurious radiation.
Patent GB-2222686-A (GB)
Title: Inclinometers
Inventor: RYAN PAUL THOMAS
IPC: A61K31/22
Filed: 1989-11-10
Abstract: In an inclinometer which comprises a capsule (3) with a conductive liquid, an electrical signal is applied between two connected together electrodes (C, D) and one, and then the other, of two further electrodes (A, B) to derive a signal indicative of the degree of immersion of the electrode A, and then the electrode B within the liquid. The ratio of these signals indicates the inclination of the capsule and relative to the gap between electrodes A, B. By reconfiguring the electrodes A-D, to measure the degree of immersion of electrodes C and D, the sensor is able to sense any angle of inclination about the reference axis. The capsule (i) compensates for thermal effects by expanding to keep the level of liquid constant. <IMAGE>

Title: Electro- magnetically operable valve
Inventor: KNIGHT ANDREW ROGER
IPC: F02M59/46
Filed: 1991-05-10
Abstract: An electro-magnetically operable fluid control valve has a pair of valve components 18, 22, the component 18 being slidable in a bore 11 of a supporting body. The component 18 is secured to an armature 17 associated with a solenoid 15 mounted on the supporting body. The component 22 is slidable in a further bore 19 formed in the component 18, the further bore defining part of the flow path, 27 to 21, of the valve and defining a seating engagable by the component 22. Attached to the component 22 is a cross bar 24 which is engagable with a stop surface to limit the upward movement of the component 22. When the solenoid is energised the component 18 moves upwardly so that the seating is engaged with the component 22 to prevent fluid flow. In a second embodiment Fig. 3 (not shown) the operation of the two valve components is reversed with the outer component being fixed and the inner component secured to an armature (29). <IMAGE>

Title: Flow measurement in medium of non-uniform electrical resistance
Inventor: LUCAS GARY PETER
IPC: G01F1/64
Filed: 1992-03-06
Abstract: The rate of flow of an electrically conductive non-uniform fluid is determined by cross-correlation of the resistance of the fluid measured at two spaced points 21 in the direction of flow. The method is particularly suitable for use in measuring the rate of flow from oil wells which produce an oil-in-water suspension with a high dissolved-salt content and replaces the correlation technique using capacitive measurements used on water-in-oil dispersions. Two spaced pairs 23 of conductivity electrodes are mounted on elongate former 22 and the former is mounted centrally in an oil well. Each electrode is preferably 5-20 mm in length with the electrodes of each pair spaced by 5-10 mm and the pairs spaced by 20-200 mm. Diameter of the former is 20-70 mm and the electrodes are preferably of titanium or plasticised titanium. The resistance is preferably measured using an AC voltage of 10KHz. <IMAGE>

Title: Treating waste
Inventor: COLLIER PHILIP JOHN
IPC: B01F7/00
Filed: 1993-03-25

Patent GB-2277635-A (GB)
Title: Magnet arrangements
Inventor: WARD KEVIN DENNIS
IPC: H01J23/087
Filed: 1993-04-28
Abstract: Magnet arrangements used in PPM focusing systems, for example, with electron beam tube devices, include a stack of cylindrical magnets 1 having pole pieces 2 interposed between them. The pole pieces are configured so as to have a Curie temperature Tc which is non-uniform in a radial direction. The inner portion 3 of the pole piece discs is of iron having a relatively high Tc and the outer portion 4 is of nickel iron having a lower Curie temperature. At relatively low operating temperatures, the magnetisation of the inner and outer disc pieces remains substantially constant. At higher temperatures, the magnetisation of the outer portion 4 decreases hence causing flux to be concentrated to the inside of the arrangement along the longitudinal axis X-X. With increasing temperature, the strength of the magnet 1 also decreases. These two effects compensate for each other to produce a substantially temperature invariant magnetic field along the axis X-X. In other arrangements, the change in temperature Tc across the pole piece discs is gradual. <IMAGE>
Patent GB-2267342-A (GB)
Title: Smoke detector
Inventor: NAGASHIMA TETSUYA
IPC: G08B17/103
Filed: 1993-05-26
Abstract: A photoelectric smoke detector responsive to transmission of light from a source 10 reflected back by a mirror 2 compensates for, or is insensitive to, light from the source back-scattered by an object 9. As shown, the mirror 2 is a retroreflector and a detector 13 is positioned to receive retro-reflected light from only one 10 of two sources 10, 30 which are alternately energised. The object 9 however scatters light from either source equally to the detector 13, so that when the source 30 is energised such scattering can be measured and then used to compensate the other measurements which comprise both reflected and scattered light. Discrimination in other embodiments is effected on the basis of wavelength (Figures 8-10; 11), polarisation (Figures 12, 13; 14, 15; 16) or chopping the detection beam (Figures 17, 18; 19). Switching between two radiation paths allows a compensation to be calculated; alternatively, single-path arrangements involving changing wavelength (Figures 20-24) or polarisation (Figure 25) at the reflector may simply reject object-scattered light which is not so changed. <IMAGE>
